API 6D Gear Operated Pipeline Pigging Ball Valve

API 6D Gear Operated Pipeline Pigging Ball Valve

    The SV API 6D pipeline pigging ball valve is a new type valve designed basis on top entry trunnion mounted ball valve and used for launching and receiving pipeline cleaning pig. 

    The SV pigging valve is widely used as special tool for pipeline constructing, cleaning, maintenance, inspection and management in industries of petroleum, chemical, city gas, water supply, printing and dyeing, food etc.

    Pipeline cleaning, emptying, isolation and delivering service in sequence will be much easier after cooperated with pigging ball valve.

  • Features
  • Specification

  • The SV cleaning pigging valve is the standard pigging valve; the area of ball bore is approx 25% larger than the flow area of pipe; barrier strips in one end of ball bore stop the pipeline pigging but don’t influence the flow of medium to keep continual medium flow when pigging; Cleaning pigging valve can be used as cut off ball valve;
  • The SV bypass pigging valve has two oval-shaped channels in the ball perpendicular to the ball bore with 25% flow area of pipe so that the flow won’t be cut off when launching or receiving pipeline pigging; bypass pigging valve can’t be used as cut off ball valve;
  • The SV isolating pigging valve with 3% larger than flow area of pipeline is used to isolating and delivering medium in sequence; Isolating pigging valve has another seal inside the ball bore when the pipeline pigging arriving the ball bore to achieve isolation;
  • Top entry body makes body without leakage and maintenance online without removing from pipeline
  • Trunnion mounted ball valves with double block and double bleeds function;
  • Stem free from ball thrust force; stem rotates freely, small torque, easy valve operation;
  • Fire safe, anti-static and anti-blowout stem design;
  • Easy to open or close port blind cover;
  • Excellent seal with zero leakage;
  • Interlocking design ensures safe operation.
